EP1K100QI208-2 Descripción general
A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit containing an array of configurable logic blocks (CLBs), programmable interconnect, and embedded memory blocks that can be re-programmed to implement any digital logic function. FPGAs occupy the programmable-logic tier of the broader digital IC hierarchy: gate array < FPGA < CPLD < programmable SoC. Compared to ASICs, FPGAs deliver lower NRE cost and faster time-to-market but trade off raw clock speed and per-unit cost. The ACEX-1K family is positioned for high-volume, cost-sensitive glue logic, bus bridging, and DSP preprocessing in industrial and telecom equipment.
Key features include 624 Logic Array Blocks (LABs), 147 user I/Os, dual-port embedded array blocks (EABs) that can be configured as RAM, ROM, or FIFO, and four low-skew global clock networks. Maximum toggle performance is rated around 250 MHz, with on-chip phase-locked loops (PLLs) for clock synthesis. The 208-pin PQFP (also referenced as BFQFP / QFP-208) package provides a 0.5 mm pitch suitable for conventional SMT assembly lines.
The EP1K100QI208-2 is configured through the Altera Quartus design suite (legacy: MAX+PLUS II). Boundary-scan (IEEE 1149.1 JTAG) is supported, and the device is in-system programmable via JTAG or configuration devices such as the EPC2. Application domains include industrial control, telecom interface cards, glue logic for embedded processors, and legacy glue logic replacements for 5V-tolerant 74-series designs.
When designing with this part, ensure 2.5 V core decoupling with 0.1 uF ceramic capacitors placed as close to each VCCINT pin as possible, separate VCCIO rails per bank, and use of the Altera configuration device for stand-alone boot. The device is NRND/last-time-buy in many channels - confirm lifecycle before new designs.

Aplicaciones típicas
EP1K100QI208-2 es adecuado para 6 aplicacións: Industrial Control Logic and Glue Logic, Telecom Interface Card and Bridging, Legacy 5V-Tolerant Logic Replacement, DSP Preprocessing and FIR Filtering, JTAG-Based In-System Programming Hub, Aerospace/Military Legacy Avionics.
Industrial Control Logic and Glue Logic
The EP1K100QI208-2 is well suited for industrial control glue logic where 4,992 logic elements and 147 user I/Os are sufficient for state machines, encoder/counter chains, and protocol bridging. Its 250 MHz toggle rate and -40C to +85C industrial temperature grade cover factory floor environments, while 5V-tolerant I/O banks simplify interfacing to legacy 74-series logic and opto-isolated industrial I/O. Power is delivered from a single 2.5 V core rail with per-bank VCCIO. Industrial engineers value the 208-pin PQFP package because it is hand-rework-friendly for field service and supports conventional IR-reflow profiles on thick 2-layer boards.
Recomendado
Telecom Interface Card and Bridging
The EP1K100QI208-2's 49,152 bits of dual-port EAB memory and 250 MHz performance make it a strong fit for telecom interface cards performing bus conversion between legacy PCI, H.110, and proprietary backplanes. The 147 user I/Os comfortably drive 32-bit data buses plus control signals, and the four global clock networks simplify distribution of recovered clocks across the design. The 208-PQFP package supports the conventional SMT process used by telecom line-card manufacturers. Compared with a fixed-function ASIC, the FPGA reduces NRE cost and supports last-minute protocol changes during carrier qualification cycles.
Recomendado
Legacy 5V-Tolerant Logic Replacement
The EP1K100QI208-2 supports 5V-tolerant I/O via VCCIO bank supplies at 3.3 V or 5 V, making it ideal for replacing aging 74F/74AS/74LS TTL glue logic on legacy boards. Engineers can absorb hundreds of discrete 74-series chips into one FPGA, reducing board area, power, and BOM cost while gaining design flexibility. The 208-PQFP package remains SMT-compatible with through-hole-suitable 0.5 mm pitch, and JTAG programming allows in-system firmware updates during the long lifecycle of industrial and military equipment. Quartus II preserves all VHDL/Verilog IP for forward migration if the device ever needs to be replaced by Cyclone series.
Recomendado
DSP Preprocessing and FIR Filtering
The EP1K100QI208-2's 49,152 bits of dual-port EAB memory and 624 LABs deliver enough arithmetic resources for moderate DSP preprocessing tasks such as FIR filters, FFT pre-processing, and signal conditioning in instrumentation. At 250 MHz toggle rate the device can implement 16-bit FIR filters at sample rates up to ~50 MSPS. The 147 user I/Os allow direct connection to high-speed ADCs and DACs without external bus multiplexers. Engineers select the PQFP package when prototyping DSP algorithms before committing to a finer-pitch BGA for production; the same RTL can then be retargeted to Cyclone with no algorithmic changes.
Recomendado
JTAG-Based In-System Programming Hub
The EP1K100QI208-2 can serve as a JTAG hub or boundary-scan controller in test fixtures and programming stations. Its full IEEE 1149.1 JTAG support, multiple I/O banks, and flexible user I/O allow it to drive JTAG chains of CPLDs, flash memories, and other FPGAs on the same board. The 208-PQFP package is convenient for test fixtures because it can be socketed for quick replacement. Quartus II provides BSDL files for boundary-scan vector generation, and the same FPGA can implement TAP controllers, JTAG-to-SPI bridges, and low-speed bus arbiters concurrently.
Recomendado
Aerospace/Military Legacy Avionics
Although NRND, the EP1K100QI208-2 remains widely deployed in long-lifecycle avionics, naval, and ground-vehicle platforms where re-qualification of newer FPGAs is prohibitively expensive. Its 208-PQFP package is fully compatible with established MIL-spec PCB assembly lines, and the -40C to +85C industrial temperature range meets many commercial-military equipment specs. The 0.22 umm SRAM process is mature with known reliability data accumulated over two decades of field deployment. For these legacy platforms the EP1K100QI208-2 is sustained through last-time-buy orders and authorized distributor stock rather than new designs.

Notas de diseño
The EP1K100QI208-2 requires a clean 2.5 V +/- 5% core supply (VCCINT) and per-bank VCCIO rails (typically 3.3 V). Decoupling strategy: place one 0.1 uF X7R ceramic capacitor adjacent to every VCCINT pin and one 10 uF tantalum bulk capacitor near the package power entry. Add a ferror bead or pi-filter on the 2.5 V rail to suppress switching noise from upstream DC-DC converters. Estimated ICCINT at 250 MHz with 50% toggle is approximately 150 mA - verify with the datasheet ICC vs frequency curves for your design's switching activity factor.
The 208-PQFP package has 0.5 mm pitch gull-wing leads that demand careful PCB land pattern design. Use IPC-7351 nominal land patterns with 0.27 mm pad width and 1.50 mm pad length. Allow at least 5 mm of continuous copper pour under the package for thermal dissipation (theta_JA is approximately 28 C/W on a standard 4-layer board). Route all JTAG signals (TCK, TMS, TDI, TDO) with 50 ohm controlled impedance and keep them isolated from switching I/O to avoid programming errors.
Three pitfalls to avoid when designing with EP1K100QI208-2. First, do not confuse MSEL[0:2] pin states - they select configuration mode (AS, PS, JTAG) and must match the selected EPC2 configuration device. Second, ensure nCONFIG is pulled high through a 10 kohm resistor and de-bounced; otherwise the device may enter an indeterminate configuration state. Third, the 5V-tolerant I/O banks tolerate 5 V input only when VCCIO is 3.3 V or 5 V (not 2.5 V); connecting 5 V signals with VCCIO = 2.5 V will damage the I/O cells.
